Brandon has said that you do not need any Cosmere knowledge to understand the books, and that they can be enjoyed separately, but it will be necessary eventually to have a certain understanding of Realmatic Theory.[4][5] Elements of the cosmere are slowly being added into the books, behind the scenes, until they come into the forefront with Dragonsteel and the final Mistborn trilogy.[6]

The underlying mythology of the cosmere revolves around Adonalsium, the power of creation, which was broken into sixteen pieces called Shards. The Shards are effectively gods, and magic is derived from their power.

A map of Shadesmar--a part of the Cognitive Realm[7]--from Roshar's perspective. Expanses on this map represent other planets in the cosmere.

The structure and physics of the cosmere are the same as our own, but the main story of the cosmere occurs in a compact dwarf galaxy, meaning it has many fewer stars and systems than our galaxy.[8] Time flows the same in the cosmere (except under special magical effects, such as Allomanticcadmium and bendalloy).[9]

There are ten primary planets in the cosmere, sometimes called Shardworlds, as the Shards of Adonalsium play major roles there.[10] There are inhabited worlds with no Shards on them, and some planets may only have Splinters of a Shard on them.[10] Planets without Shards are generally referred to "minor Shardworlds". On all cosmere planets, magic is called Investiture, a word that means something has gained a portion of Adonalsium's magic.[11] All magic we've seen has been derived from the Shard's--or Adonalsium's--power.[12] Specific magic systems, like Allomancy or Surgebinding, are termed "manifestations of Investiture."[13] On minor worlds, people don't utilize Investiture directly, and magic is more something people interact with through nature.[14]

The physical universe of the cosmere only tells one part of the story. In fact, there are three Realms of existence: the Physical Realm, the Cognitive Realm, and the Spiritual Realm that all coexist simultaneously, and everything has aspects in each of these Realms.[15] Even planets themselves have souls.[16] Investiture transcends all three of these Realms.[17] The Cognitive Realm and Shadesmar allows for travel between cosmere planets.[18] Also, there is something beyond the Three Realms, where people "pass on," which Shards can potentially touch,[19] but Brandon does not wish to reveal anything about it.[20]

There are also other forces outside of things derived from Adonalsium. One is a force that opposes Adonalsium, which still exists[21], and some say there are "subtle forces" being manifest, separate from Adonalsium, perhaps referring to the God Beyond.[22][23]

There are currently eleven known planets in the cosmere. Three of these planets (Ashyn, Braize, and Roshar) are known to be in the same solar system.[24] Two of these, Threnody and First of the Sun, are minor Shardworlds.[25] Note that the following chart lists Shards currently on the planet, and may have had other Shards there at other points in time.

*Harmony is the combination of two Shards, Ruin and Preservation, that are intermingled since they are under the control of one individual.[36] Harmony is referred to as a Shard,[37] though it is not one of the original sixteen Shards of Adonalsium.

“ Even now, I can barely grasp the scope of all this. The events surrounding the end of the world seem even larger than the Final Empire and the people within it. I have delved and searched, and have only been able to come up with a single name: Adonalsium. Who, or what, it was, I do not yet know.
”

Little is known of the extremely distant past of the cosmere: the time before the Shattering of Adonalsium and the Shards. It is not clear who or what Adonalsium was/is. It is unclear whether it is a force, a person, a god, or the metaphysical god. It isn't clear if it was self-aware or not. Regardless, it is sometimes described as the power of creation,[39] possibly a thing with incredible amounts of Investiture (since Investiture is a piece of Adonalsium[11]), and a power which does not vanish.[40][41]

Humans existed on worlds before this time,[42] though how many is unknown. At the very least, the first humans were on Yolen.[43]Hoid in particular is from Yolen.[44][45] All cosmere planets existed prior to the Shattering, and their names existed before the Shards got there.[46][47] Magic (Investiture) also existed prior to the Shattering, though its form was different.[48] The technology level of this society prior to the Shattering was less than present day Earth's.[49]

There was a force that opposes Adonalsium[21] which created a weapon,[50] but important specifics, such as if it is still around, or if it had played a role in Adonalsium's Shattering, are unknown. There was once a plot to destroy Adonalsium, which failed.[51]

Through unknown means, Adonalsium was broken, in an event called the Shattering. Hoid was present,[52] and due to Hoid being from Yolen, it is thought that this event occurred on Yolen. This Shattering happened intentionally,[53] and occurred all at once.[54]

“ Ati was once a kind and generous man, and you saw what became of him.
”

Adonalsium split into sixteen pieces, referred to as Shards of Adonalsium, each taking a particular facet, or intent, of the greater power of Adonalsium. Sixteen people took up those Shards, effectively ascending into godhood. Hoid and the Recipient knew these sixteen people prior to their Ascension, as they were familiar with their original names.[56][57][58] Some of these individuals and the Shard they took up are: Aona (Devotion), Skai (Dominion), Ati (Ruin), Leras (Preservation), Tanavast (Honor), and Rayse (Odium). Another individual who took up a Shard was Bavadin, whose Shard's intent has been revealed in interviews with Brandon to be Autonomy . There are two more known Shards: Cultivation, whose holder is female but otherwise unknown, and Endowment, whose holder is Edgli.

It was not random who took up the Shards,[59] and there was some sort of design in the way Adonalsium was split.[60]

It turned out that, though the power of a Shard required a mind to control it, the specific intent of the Shard would slowly warp the mind of those that hold it.[55][61] It is not known whether the holders of the Shards knew this would be the case initially. Eventually, the people who took up the Shards would simply be referred to as their Shard's name, and referred to as Shards.

At some point, some Shards traveled to other worlds. The Shards were now the primary source of magic in the cosmere,[12] and so they Invested some planets with their power, and in some cases, created humans and other species.[62]

The exact timeline of what the Shards did after the Shattering is not clear. Shards settled on specific planets, but could have gone to other places before residing upon the worlds they now stay.

Endowment was the only Shard who traveled to Nalthis.[29][63] At some point during the history of Nalthis, Endowment began intentionally splitting its power, creating what are called Splinters. These Splinters were the divine Breath, which made the Returned.[29]

Ruin and Preservation, having intents that opposed each other so perfectly,[66] found themselves drawn to each other, which caused conflict. If Ruin tried to destroy, Preservation would stop him, and vice versa. At some point they both ended up on Scadrial, but they could not act much without the other.[67]

They came up with a deal: they would work together to create life, with the condition that Ruin would eventually get to destroy them.[69] But Preservation wanted to create life that they had seen before--humanity[62]--and creating sapient life required more energy. Ruin was not willing to put in that extra energy, so Preservation did. This led to Preservation being slightly weaker than Ruin. Because of this, Preservation knew that Ruin would inevitably triumph and destroy what they created.[69]

Preservation couldn't stand to let Ruin destroy their creations, so he felt the need to do anything to stop this from happening. Preservation, then, betrayed Ruin. Preservation could not destroy Ruin--doing that sort of assault would result in both Ruin and Preservation's death, and the Shard had influenced Preservation's mind too much for him to do something so destructive. In order to stop Ruin, he needed another plan.

Preservation attacked Ruin with his mental power--the distinct mind controlling the Shard's power, rather than the power itself. This would trap Ruin's mind, making him mostly impotent.[70] However, it cost almost all of Preservation's mind. Preservation knew that the moment he did this attack, he would not be able to help life on Scadrial. Preservation saw the future, creating the Terris Prophecies, to give hope to humanity, and to let humanity know that he had a plan in mind.[71] He also altered Allomancy so that there would be atium (and malatium) Mistings,[72][73] and set up his power--the mists--to Snap those Allomancers.[74] And with that, Preservation gave up his mind, imprisoning Ruin in the newly created Well of Ascension.

“ One need only look at the aftermath of his brief visit to Sel to see proof of what I say. In case you have turned a blind eye to that disaster, know that Aona and Skai are both dead, and that which they held has been Splintered. Presumably to prevent anyone from rising up to challenge Rayse.
”

Odium wanted to become the strongest being in the cosmere.[75][76] He realized that if he ever took up another Shard, that Shard would change him, and Odium preferred his own.[61] So, in his quest to become god of the cosmere, instead of absorbing all the other fifteen Shards, he decided to destroy the other Shards.[75] He developed a way to Splinter a Shard's power, and in the process, killing its holder.[33]

“ He bears the weight of God's own divine hatred, separated from the virtues that gave it context. He is what we made him to be, old friend. And that is what he, unfortunately, wished to become.
”

Odium traveled to Sel for a short time to attack Devotion and Dominion, and Odium Splintered them.[33] This left a lot of energy on Sel, and, with no release valve and entity to control the power, Shadesmar became incredibly hazardous on Sel.[78] Selish magic itself changed,[65] and perhaps the Dor was created--a force that can be drawn upon but with no controlling entity. Odium left Sel after this event, and did not Invest any of his power on the planet.[78]

At some point--perhaps before Odium's actions on Sel, or after--Honor and Cultivation went to Roshar together.[31] Later, Odium went to the Greater Roshar system.[79] Before this, Odium did not settle on a specific planet, but on Roshar, he Invested his power, and his magics are felt there,[80] and perhaps other worlds in the system. Devastating wars called the Desolations were fought over Roshar, between Odium's Voidbringers and Honor's Heralds and Knights Radiant.[81] Cultivation's exact role in the Desolations is not clear, but Honor and Cultivation were a romantic item.[31]

Odium eventually killed Honor, using the same method as he did with Devotion and Dominion.[82] However, Honor was crafty, and even though Honor perished, Odium was then trapped on the Greater Rosharan System.[57] At some point, Odium ended up being on Braize, which he is currently located, prior to the True Desolation.[28] Cultivation, on the other hand, survived Odium, and is still alive.[83] Odium has not killed another Shard after this point.[58]

Before Odium's confinement on Greater Roshar, at an some unknown time, he also killed another Shard in addition to Devotion, Dominion, and Honor.[84] There is also a Shard who just wants to survive, presumably against Odium's onslaught.[85]

“ For I have never been dedicated to a more important purpose, and the very pillars of the sky will shake with the results of our war here. I ask again. Support me. Do not stand aside and let disaster consume more lives.
”

Hoid was deeply concerned about Odium's involvement on Sel, and thought that his war would lead to devastate the whole cosmere.[86] He sent a letter[56][61] to a person (possibly a dragon[87]) to call off his "friends of the Seventeenth Shard" and help join Hoid.[88] The recipient of Hoid's original letter did not see things as Hoid, and said that the reason these events have occurred is because of their involvement.[89] As such, he advocated nonintervention,[90] where Hoid meddled a great deal, on all main worlds.

The Seventeenth Shard are a group of Worldhoppers moving between planets using various magics, and are perhaps led by the Recipient.[88] Their members are from many worlds,[91] including Scadrial, Taldain, and Sel. They searched for Hoid on Roshar shortly before the Everstorm was summoned.[92] They may also be nonintervenionists, due to their possible relationship with the Recipient.[88]

There is also Khriss, a Worldhopper who is the most knowledgeable person in the cosmere, by far.[93] She writes all the Ars Arcanums,[94][95] and as such, is a member of the Seventeenth Shard.[96] She has an employee, Nazh, who, among other things, draws and annotates maps, and collects other things for Khriss.[97][95] Their motivations--and exact relationship with the Seventeenth Shard--are not clear.

However, there is an end goal of the Seventeenth Shard.[98] In the immediate future, they fear Hoid's purpose will not align with theirs, and so they hunt him down.[99]

There is not a universal language for all cosmere worlds that these worldhoppers speak.[100]

On Scadrial, the Well of Ascension, that power that came from Preservation, could be utilized by humanity. For much of Classical Scadrian history, a person called the Hero of Ages by the Terris Prophecies would take up the power and become a protector of mankind. They would live the rest of their lives blessing people with the power of Preservation, renewing Ruin's prison, and watch over the world.[101] The power did not vanish, instead returning every 1024 years.[102]

Ruin was keenly interested in the Well of Ascension. If he could get a person to hold the power there, but instead of utilize the power, release it, then the prison on Ruin's mind would vanish, and he would then be free to finally destroy the world.[103] To do this, Ruin manipulated the Terris Prophecies over a long period of time. He made it so the Hero of Ages would include the "sacred piercings," actually Hemalurgic piercings, so he could influence the Hero.[104] More importantly, Ruin changed the Prophecies extensively so that the Well and the Hero's purpose was obscured.[101] Now the Hero was supposed to take the Well's power and release it.

Then, Ruin drove the world into desperate straits so that people would believe in a hero of ancient prophecy. If he fought Preservation, the mists--the Shard of Preservation's direct essence--which still protected the land would oppose him. So, he used Preservation to his advantage: the mists Snapped Allomancers, and people misinterpreted the mists as a negative thing. Instead of fighting against the mists' action, Ruin enhanced them, bringing the death of plants, and causing the threat that became the Deepness.[74]

Thus, when a TerrisWorldbringer, Kwaan, claimed that Alendi was the Hero of Ages,[105] Ruin saw an opportunity. He altered the Terris Prophecies to fit Alendi more perfectly.[106] Alendi came to persuade kings and all the Worldbringers who denied him that he was the Hero, and under the threat of the Deepness, Alendi was their leader.[107][108] So, to defeat the threat of the Deepness, Alendi traveled to the mountains of Terris, where the Well of Ascension lay, to take up the power, and release it to eliminate the Deepness.[109]

“ Alendi must not reach the Well of Ascension, for he must not be allowed to release the thing that is imprisoned there.
”

Kwaan, however, had a fabled memory, and noticed that the Prophecies had changed.[112][113] But Kwaan was not able to persuade Alendi that he was not, in fact, the Hero after they had argued for so long to prove that he was the hero of legend.[114] So Kwaan, knowing something was awry with the Well, tasked a nephew, Rashek, who hated Alendi, to be Alendi's guide through the mountains.[115][116] Since Rashek was a Feruchemist, Rashek and his friends were easy picks for Alendi. If Rashek could not lead Alendi astray, he was to kill him.[117]

And Rashek did murder Alendi. Rashek took the power of the Well himself, and in those few moments of Ascension, he tried to stop the Deepness by moving Scadrial itself closer to the sun, to burn the mists. To counteract the heat, he created the Ashmounts.[118] He also altered humans on Scadrial, creating skaa and nobles. He learned of the Metallic Arts, developing Hemalurgic constructs, and with the discovery of Allomancy, he figured out a way to combine Allomancy and his Feruchemy to become immortal (through Compounding).[119] Rashek would be the Lord Ruler, the Hero of Ages, and protect the world from Ruin.[120]

“ One can see Ruin's craftiness in the meticulousness of his planning. He managed to orchestrate the downfall of the Lord Ruler only a short time before Preservation's power returned to the Well of Ascension. And then, within a few years of that event, he had freed himself. On the time scale of gods and their power, this very tricky timing was as precise as an expert cut performed by the most talented of surgeons.
”

Ruin saw the Lord Ruler's poor use of the power and saw that the Lord Ruler would be an agent of spectacular destruction.[122] So, subtly, Ruin manipulated him to destroy. The Lord Ruler did do things to stymie Ruin, such as hiding atium,[123] but Ruin's subtle manipulations took a toll on the man, and led to him subjugating his own people, among other atrocities. But as destructive as the Lord Ruler was, a thousand years later, the Well of Ascension was about to refill. The Lord Ruler planned to retake the Well's power,[124] and Ruin would not have that happen.

So, Ruin plotted the Lord Ruler's downfall. He subtly put in Kelsier's mind the idea of an "eleventh metal" to the ten known Allomantic metals of the time.[125][126] This, combined with Kelsier's desire to see his dead wife avenged and her dreams of a world without ash be a reality, led Kelsier to seek to kill the Lord Ruler. He formed his crew, consisting of many, but including Vin, a skaa Mistborn who Ruin manipulated; Marsh, his brother; and Sazed, a Terris Keeper, who studied the past before the Lord Ruler. In the process of leading the skaa to revolt against the Final Empire, the Lord Ruler killed Kelsier.[127] Vin confronted the Lord Ruler, and using the power of the "Eleventh metal", discovered that the Lord Ruler was a Feruchemist.[128] She somehow drew upon the mists and pushed the Lord Ruler's metalminds away, leading to his death a mere two years before the Well was replenished.[128]

Ruin now needed a person who could hold the Well's power. The servants he could touch most easily through Hemalurgy, the Steel Inquisitors, could not hold Preservation's power,[129] so Ruin chose Vin to do it. Ruin, early in Vin's life, had caused her mother to go insane, killing her sister with an earring. The earring turned out to be a Hemalurgic spike, so Ruin could influence Vin. The spike, through increased bronze Allomancy, allowed Vin to hear the pulses of the Well of Ascension.[130] Ruin strengthened the mists again to recreate the threat of the Deepness, and influenced events so that Vin seemed like the Hero of Ages.

With all this, Ruin led Vin and Sazed to the Well of Ascension for them to "save" the world once again. However, Preservation had a shadow of his mind left, and in the form of a mist spirit, tried to foil Ruin.[131] Preservation even wounded Vin's husband, Elend, at the Well so Vin would use the power to heal Elend instead of releasing it. But Vin did what the prophecies supposedly asked, releasing the power.[132]

Ruin could now directly affect the world, but the power of Preservation--in the form of the mists--still protected the planet.[133] Ruin had been weakened since the Lord Ruler hid his essence, atium, and so Ruin and Preservation were balanced again. Ruin could not find the atium personally, as he could not see metal, and the Steel Inquisitors, had spikes in their eyes, and so had this same flaw. So, Ruin continued to use his pawn, Vin, along with Elend, to find the atium for him.[124]

Ruin did not know that Preservation had actually selected Vin to take up his power,[130] which enabled Vin to draw upon the mists--Preservation--directly.[134] Unfortunately, Vin could not use this power with her earring being a Hemalurgic spike, as Hemalurgy, being of Ruin, pushed away Preservation.[135]

In those final days, the shadow of Preservation's mind that remained communicated with Elend, and then passed.[136] This had the potential to be a catastrophic event: when a Shard lacks a mind controlling it, and the power has no "release," it is incredibly dangerous, as happened on Sel when Odium destroyed Devotion and Dominion.[78] Fortunately, Kelsier, who had not passed on beyond the Three Realms, held onto Preservation's power for just a little longer, until Vin could take it up.[137]

Vin eventually caught onto Ruin's ploys, and would not find the atium for him.[138] Because of this, Ruin sent his Inquisitors, along with Marsh, his main Inquisitor, to kill Vin.[139] Marsh, though almost entirely under Ruin's direct control, held a small bit of himself back, and he used that shred of humanity to tear the Hemalurgic earring from her.[139] Vin could now access the mists--Preservation's power--fully, and upon burning it, she ascended, becoming Preservation.[140]

Upon Vin's ascension, she tried to oppose Ruin, but learned that she could not do much, for Ruin would oppose her.[62] On the ground, Elend and Sazed discovered the atium, and Ruin immediately sent his forces to destroy them.[142][143] Ruin, through Marsh, killed Elend, and Vin realized Preservation's plan. Preservation needed someone who could preserve, but also destroy, and Preservation was too touched by his Shard to destroy Ruin. Vin knew she had little left to live for without Elend, and so, directly attacked Ruin with her power. She pressed in, not shying back, and in the assault, killed Ruin and herself in the process.[141]

Sazed, on the ground at the battle, saw the corpses of Ati and Vin, with the power of their Shards leaking from their bodies, and Sazed took up both Shards together. The power did not vanish as the Well of Ascension's power did; these were the Shards themselves, which, under the control of one mind, could both preserve and destroy, or create. Using the knowledge from his metalminds, he began to remake the world, and undid the damage the Lord Ruler did to Scadrial.[144] This event will later be known as the Catacendre, meaning "the end of the ash".[145] He then created a paradise for them to live in.[146][147] The conflict on Scadrial had vanished, for now.

Now under the control of one mind, Ruin and Preservation's power began to intermingle, and Sazed became known as Harmony.[36] It is considered a single Shard, much like a king of two countries is still just one king.[37]

Odium became aware of Harmony, is scared of him,[148] and is making plans regarding him.[149]

“ I wrote thirteen novels before I sold one. I spent a lot of time practicing and learning, and I love big epic grand series. However, you know, you can't grow up reading the Wheel of Time without loving big series, but advice I heard early on was, selling a big series is actually pretty hard from a new author and if you, for instance, spend your life and you write like six books in the same series, and you send off the first book to someone and they don't buy it, you can't really send them the second book. ... I wanted to expand my chances, and so I wrote thirteen novels in different worlds, all with their own different magic systems and own characters. But secretly I loved the grand epic, and so I started connecting all these worlds during my unpublished era, and telling a hidden epic behind them all that I was setting up for.
”

When Brandon was beginning writing and trying to get published, he loved gigantic epic fantasy series. He knew, however, that starting with a big series might not be the best idea. If he wrote four books in a series, and the first one didn't get published, he couldn't submit his sequels.[150] He decided instead to focus on standalones and trilogies. Not only would they be easier to market to publishers, but Brandon also wanted people to trust his writing before digging into something bigger.[151]

He still loved the idea of a huge epic series, so he decided to create a "hidden" epic to link his novels together. His ideas for this connected universe--the cosmere--came about when he wrote Elantris, Dragonsteel, White Sand, and Mythwalker (which became Warbreaker).[150] Brandon had seen other authors who made a single universe for all their books, like Isaac Asimov, but Brandon didn't like how Asimov had to retcon and shoehorn things together to connect their books. Brandon wanted to do the cosmere from the ground-up, so it would always be consistent.[151]

Some ideas that came into the worldbuilding of the cosmere came from Plato's theory of forms, which contributed to the idea of Realmatic Theory, and the idea of the Physical, Cognitive, and Spiritual Realms. In this, the distinction of what is perceived as "ideal" and what is the true ideal is important: true ideals have much to do with the Spiritual Realm, while people's perception of ideals deals with the Cognitive Realm. Another influences is Spinoza, with the idea that God is in everything.[152] Brandon also incorporated the idea of a "unifying theory of everything" from physics to the magic in the cosmere. All magics have underlying rules, and are derived from a single unified theory of magic.[153]

There is a distinct beginning, middle, and end to the cosmere sequence, and a clear sequence Brandon wants to tell.[154] There's about 36 main cosmere books, and Brandon has three "core" cosmere series: Dragonsteel, Mistborn, and the Stormlight Archive,[155][156] which are well-planned out.[157] Dragonsteel is the start of the cosmere sequence that will tell Hoid's backstory[158] and, presumably, the Shattering of Adonalsium. Mistborn will have three big trilogies, its last one being science fiction, deals heavily with the cosmere[159] and has travel between the different planets of the cosmere.[160] Stormlight Archive is set in the middle of the cosmere sequence.[161] Generally, the cosmere will not come into the forefront until Dragonsteel or the final Mistborn trilogy,[6] and the final Mistborn trilogy is one of the last cosmere series, if not the last. Brandon has said it will all fit together, and thinks we'll be impressed.[162]

“ I hope that people will stick with me for all these books, because I'll do a lot of them. But they will fit together in some really cool ways once they are all done. I think you'll be very very impressed, but that's a while off.
”

At the start of Brandon's career, he wrote cosmere novels in chronological order, but there are books that are skipped, like Dragonsteel and White Sand,[161] some of his earlier, unpublished novels. (Those unpublished novels would need to be rewritten from scratch, much like Brandon rewrote The Way of Kings.[163]) He wanted these cosmere novels to not require knowledge of previous books in the hidden epic of the cosmere. Generally, clues to the cosmere are currently easter eggs, and will not be in the forefront. However, more hints to the greater universe are inevitable, and eventually the worlds will cross over and interact,[164] perhaps in the last Mistborn trilogy.

Hoid, a character who appears in each cosmere novel, is one such easter egg. It is not random where he is; Brandon has said that if Hoid appears in a place, that place is about to be very dangerous.[5] Hoid is doing things behind the scenes, and at some point, we might have Hoid short stories explaining what is doing and why.[165][44] There are also other people who cross between worlds that eventually Brandon thinks will be much clearer later, once we see those characters more.[166] But for now, they are easter eggs.

Brandon does not feel that the cosmere is restrictive to his writing.[162] Though cosmere novels are intensive, as they require more planning and specific rules[167] (Brandon has continuity editors, like Peter and Karen Ahlstrom, on his internal wiki to keep it straight[168]), he feels that if he needs to take a break, he can just write a non-cosmere novel. Those "breather" novels are used to keep Brandon creatively engaged, and are almost always non-cosmere.[169] If there is a concept he really wants to write but doesn't fit in the limitations of the cosmere, he moves it into a non-cosmere book.[170]

The Rithmatist used to be a cosmere novel, and its magics take many elements from cosmere magics,[171] but Brandon decided that Earth is not in the cosmere, nor any alternate Earths.[172]

Eventually, there will be an official timeline for cosmere events.[173] There will probably be a cosmere encyclopedia at some point, but not for a long time.[174] It is more likely there will be Stormlight and Mistborn worldbooks first.[175] There will eventually be a Shadesmar map and star map for the cosmere that is released.[176]

Brandon does generally plan out which cosmere hints to give to fans, but sometimes he gives hints on the fly. Usually, fans are able to pry much more than he initially intended to tell.[177]

Elantris sequel and Elantris finale, the sequels to Elantris. These will be written in between the break of Stormlight 5 and Stormlight 6, and needs to be written before the next Mistborn trilogy can be written.[178]

Era 3 Mistborn trilogy, the trilogy with Allomancy in a modern, 1980s technology level. This will be written in between the break of Stormlight 5 and Stormlight 6.[178]

Dark One, a young adult "series" that is centered on the individual destined to destroy the world, rather than save it.[178]

Dragonsteel, the origin story of Hoid. This will not be written until after the Stormlight Archive is finished.[178]

Era 4 Mistborn trilogy, the science fiction trilogy. Hoid is a main character of this.[158] This will be one of the last known cosmere sequence, chronologically, and has much to do with the worlds coming together.[6]

The exact order of cosmere stories is difficult, as Brandon has typically not canonized it, as he wants to remain flexible for the behind-the-scenes stories with Worldhoppers and other unpublished works. An uncanonical timeline of the cosmere has the distance between the Shattering and the breaking of the Oathpact is about 6000 years.[181] Do not take that for exact fact, but it probably means that these time scales are in thousands of years, not millions of years.

Generally, cosmere novels have been written chronologically, so Elantris is before era 1 Mistborn books, which is before Warbreaker. However, Brandon will go back and add other works into this scheme, like Dragonsteel and White Sand.[161]

Dragonsteel will be the beginning, before Elantris. Mistborn Era 3--the modern day trilogy--will be between the two halves of Stormlight Archive. Mistborn Era 4, the scifi trilogy is at the end.[156]Nightblood, the Warbreaker sequel, will be set closer to Warbreaker than Stormlight Archive.[185]

The capitalization of the word "cosmere" is inconsistent at best from official sources. Generally, in the novels, like Stormlight Archive books, cosmere is uncapitalized,[186][187] but exclusively in The Alloy of Law, its Ars Arcanum refers to it with a capital C.[13] Adding to the confusion, these Ars Arcanums are written by the same person,[94] and Words of Radiance's Ars Arcanum uses lowercase.[188]

From interviews where Brandon types responses, Brandon sometimes capitalizes cosmere,[169] and sometimes leaves it uncapitalized.[189]Peter Ahlstrom, Brandon's assistant, has said that generally, cosmere is uncapitalized in books, but capitalized outside of them.[190]
